High Power Density AC 500kw Load Bank Orange 3 Phase Load Bank With Phase Voltage
Product Description
Automatic AC load bank main used to test the capability and aging degree for high-power ups on-line, inverter, switch power and diesel generator set for electric power, telecom department and manufacturer. It can ensure the reliability of constant power charge that adopts uniformly stepped power input, energy consumption work model and forced air-cooling model. It is of high power density, no red hot phenomenon and automatic protection function overheated. It can’t be overheated and broken when the fans stop working. The complete machine can be operated simply and maintain convenient that adopts module design. It can test voltage and current according to client’s request, and provide scientific test measures for high-power AC equipment.

Product Advantage
Real-time parameter: Current, voltage, power, power factor, frequency, time, etc could be displayed by software.
Safety monitoring: User can know the working conditions of load bank through software indicating light. When in abnormal stop protection, software will indicate the reasons of stopping.
Application
Manufacturers of standby power generators commonly use load banks to test and tune newly assembled units. When the generator has been set up in a test cell within the factory, a test engineer uses the load bank to apply a discrete, selectable electrical load to the generator and measure the response stability and endurance. During this process, the test engineer calibrates and adjusts the generator performance to ensure it meets the intended product specifications and tolerances.
